Crawl Control

Allows travel on extremely rough off-road surfaces at a fixed low speed without pressing the accelerator or brake pedal. Minimizes loss of traction or vehicle slip when driving on slippery road surfaces, helping for stable driving.

The Crawl Control indicator is lit and the slip indicator flashes when operating.

Also, the operating status and speed select status of the Crawl Control are shown on the multi- information display.

Speed modes

• LO (low mode) Effective when traveling on rocks, or descending a slope of mogul and rubble.* • MED (medium mode) Effective when ascending a slope of mogul.* • HI (high mode) Effective when ascending a slope of mogul and rubble, or travel- ing on snow, dirt, mud, sand, gravel, grass etc.* The position between low and medium modes and the position between medium and high modes can also be selected.

*: Depending on the road surface, may not be the most effective.

The Crawl Control can be operated when

• The shift lever is in any gear other than P or N.

• The four-wheel drive control switch is in L4.

• The driver’s door is closed.

Automatic system cancelation

In the following situations, the system is canceled automatically:

At that time, the buzzer will sound, the slip indicator turns off, and the Crawl Con- trol indicator flashes.

A notification will be displayed on the multi-information display for several seconds.

• When the shift lever is moved to P or N.

• When the four-wheel drive control switch is in H4.

• When the driver’s door is opened.

When turning off Crawl Control while traveling, stop the vehicle before the Crawl Control indicator turns off, or drive extremely carefully.

Function limit

• In the following situations, you will be able to use brake control to drive downhill at a fixed low speed, but you will be unable to use engine control to drive uphill at a fixed low speed.

•When the driving mode is set to second start mode.

•When the vehicle speed is higher than 6 mph (10 km/h).

• In the following situation, engine control and brake control will stop temporarily:

At that time, the Crawl Control indicator flashes.

When the vehicle speed is higher than 15 mph (25 km/h).

When the Crawl Control system is operated continuously

This may cause the brake actuator to overheat. In this case, the Crawl Control sys- tem will stop operating, a buzzer will sound, the Crawl Control indicator will turn off after flashing and the TRAC OFF will be shown on the multi-information display. In this case, quickly stop the vehicle in a safe place and give the actuator adequate time to cool off. Refrain from using the system until the message goes off. (The vehi- cle can be driven normally during this time.)

If the automatic transmission system overheats

The system will cease operation, a buzzer will sound and a warning message will be displayed to alert the driver. Stop the vehicle in a safe place until the warning mes- sage turns off.

Sounds and vibrations caused by the Crawl Control system

• A sound may be heard from the engine compartment when the engine is started or just after the vehicle begins to move. This sound does not indicate that a malfunction has occurred in Crawl Control system.

• Either of the following conditions may occur when the Crawl Control system is operating. None of these are indicators that a malfunction has occurred.

• Vibrations may be felt through the vehicle body and steering.

• A motor sound may be heard after the vehicle comes to a stop.

If the slip indicator comes on...

It may indicate a malfunction in the system. Consult your Lexus dealer.

CAUTION

When using Crawl Control

Do not rely solely on the Crawl Control. This function does not extend the vehicle’s performance limitations. Always thoroughly check the road conditions, and drive safely

These conditions may cause the system not to operate properly

When driving on the following surfaces, the system may not be able to maintain a fixed low speed, which may result in an accident:

• Extremely steep inclines.

• Extremely uneven surfaces.

• Snow-covered roads, or other slippery surfaces.
